Let me ask you....why not UEFI?

I've tried using virt-install and it still locks up.

sudo virt-install --name centos7-uefi \
   --ram 2048 --disk size=20 \
   --boot uefi \
   --location http://mirror.sigmanet.com/centos/7/os/x86_64/

Thanks for confirming.
F28 as a UEFI vm works fine.

On Hyper-V I always setup as Gen2 which is UEFI also. I do recall various problems with some CentOS installs though a few years ago. Cannot recall clearly though. Most are Gen2, so I obviously figured out whatever I was doing wrong back then.

I thought the issue on Hyper-V was related to secure boot.

Oh I forget to turn that off about 50% of the time when I make a new VM.

But no, I mean I had some various other issues, but cannot recall.

That has always sucked all the time...

It would be awesome that they add an option under generation 2 when creating the VM using Hyper-V Manager.

@black3dynamite I already have a habit of un-checking "Secure Boot" after I create the VM.

Go figure...CentOS-7 UEFI vm on Windows Server 2019 "Preview" w Hyper-V installs no problem!!!
